php_mt_seed

phpmtseed phpmtseed is a PHP mtrand seed cracker. In the most trivial invocation mode, it finds possible seeds given the very first mtrand output after possible seeding with mtsrand. With advanced invocation modes, it is also able to match multiple, non-first, and/or inexact mtrand outputs to...

CVE-2026-94107

NivoCart through 2.4.0 contains a predictable password reset token vulnerability in the forgotten.php endpoint that generates recovery codes using substrmd5mtrand, 0, 10. Attackers who know an administrator's email address can request a password reset and predict the token to gain administrative...

CVE-2026-94107 NivoCart through 2.4.0 Predictable Administrator Password Reset Token

NivoCart through 2.4.0 contains a predictable password reset token vulnerability in the forgotten.php endpoint that generates recovery codes using substrmd5mtrand, 0, 10. Attackers who know an administrator's email address can request a password reset and predict the token to gain administrative...

CVE-2026-14495: Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG)

The DoLogin Security plugin for WordPress is vulnerable to Authentication Bypass via Insufficient Randomness in all versions up to, and including, 4.3. The vulnerability exists because dologin\s::rrand seeds the Mersenne Twister with mtsranddouble microtime 1000000 — discarding the integer-second...

CVE-2025-68932: Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG)

FreshRSS is a free, self-hostable RSS aggregator. Prior to version 1.28.0, FreshRSS uses cryptographically weak random number generators mtrand and uniqid to generate remember-me authentication tokens and challenge-response nonces. This allows attackers to predict valid session tokens, leading to...

CVE-2021-39249

Invision Community aka IPS Community Suite or IP-Board before 4.6.5.1 allows reflected XSS because the filenames of uploaded files become predictable through a brute-force attack against the PHP mtrand function...

CVE-2016-3735

Piwigo is image gallery software written in PHP. When a criteria is not met on a host, piwigo defaults to usingmtrand in order to generate password reset tokens. mtrand output can be predicted after recovering the seed used to generate it. This low an unauthenticated attacker to take over an...

GHSA-XG9W-R469-M455 ZendFramework Potential Information Disclosure and Insufficient Entropy vulnerabilities

In Zend Framework 2, the Zend\Math\Rand component generates random bytes using the OpenSSL or Mcrypt extensions when available but will otherwise use PHP's mtrand function as a fallback. All outputs from mtrand are predictable for the same PHP process if an attacker can brute force the seed used ...

Name of the Vulnerable Software and Affected Versions: Zend Framework 1 affected versions not specified Description: The issue is related to insufficient entropy in random number generation methods used in various parts of the Zend Framework 1. Specifically, the methods Zend Ldap...

Use of predictable RNG for password generation

Description pkp-lib implements a password-generation function with the following line of code being integral to its functionality: PHP for ... $password .= mtrand1, 4 == 4 ? $numbersmtrand0, strlen$numbers - 1 : $lettersmtrand0, strlen$letters - 1; This relies upon mtrandlow, high; to generate a...

SUSE CVE-2011-0755

Integer overflow in the mtrand function in PHP before 5.3.4 might make it easier for context-dependent attackers to predict the return values by leveraging a script's use of a large max parameter, as demonstrated by a value that exceeds mtgetrandmax...

Insecure Random Number Generator

phpservermon/phpservermon uses an insecure random number generator. The vulnerability exists because of the insecure mtrand random number generator function in the loginWithCookieData function of User.php, allowing an attacker to guess the strings it generates...

GHSA-382V-GXJ9-FFHC Moodle uses predictable password-recovery tokens

lib/moodlelib.php in Moodle through 2.6.11, 2.7.x before 2.7.10, 2.8.x before 2.8.8, and 2.9.x before 2.9.2 relies on the PHP mtrand function to implement the randomstring and complexrandomstring functions, which makes it easier for remote attackers to predict password-recovery tokens via a...
